The mattress (100) has a core (1) which is formed with an elastic strand (2). The elastic strands are integrated into a single piece with the surrounding core. The elastic strands are formed with holes (10) in the core, where the width (b) of the cross-section of the elastic strands varies. The cross section of the elastic strands is symmetrical to a about a vertical middle axis (a). |
